UNITED STATES WILLIAM F. STELLNER, -OF,IDA1\IVILLE,ILLINOIS.-

TRAFFIC stench.

Application filed October 12, 19 22. Serial No. 594,021.

To all whom it may concern Be it known that I, WILLIAM F. STELLNER, acitizen of the United States, residing at Danville, in the county ofVermilion and State of Illinois, have invented certain new and usefulImprovements in Trafiic Signals, of which the following is aspecification.

This invention relates to traflic signals and it consists in the novelfeatures hereinafter described and claimed.

An object of the invention is to provide a signal of the characterstated which is of simple and durable structure and which may be easilyand quickly set up or removed from a roadway or street as desired.

lVhile the device is primarily intended as a traflic signal it may beused to advantage for other purposes as for instance Safety first sign,Quiet zone, Hospital, Schoolhouse Dan er Drive slow No arka a 7 3 p lng,Street names, and the like.

l/Vhen used as a trafiic dlrecting or controllin si n the si nal isrovlded with the usual words Stop and Go.

The slgnal structure comprlses a socket member which is permanentlyplanted in the circuit portion of a street or roadway. shaft or standardis slidably received in the socket member. This shaft is provided with acollar which closes the upper end of the socket member. A traffic signalcasing A is revolubly mounted on the upper end of the shaft and isprovided with angnlarly disposed side surfaces upon one of which appearsthe word Stop and upon an adjacent surface appears the word Go when thesignal is used for controlling the movement of trafiic. In use theofficer or director stands at the side of the signal and faces in thedirection from which the vehicles are approaching. With one hand heturns the signal casing to bring an intended legend of instruction toview to the occupant of an approaching vehicle and he may with the otherhand indicate the direction in which the vehicle is to proceed.

In the accompanying drawing Figure 1 is a side elevation of the trafficsignal with parts broken away and parts in section.

Figure 2 is a horizontal sectional view of the signal casing, and Figure3 1s a fragmentary vertical sectional view of the same.

As illustrated in the accompanying drawings, the signal structurecomprises a socket member 1 which is closed at the bottom and open at.the top. The socket member is adapted to be planted or mounted in thecircuit portion of a street or roadway, in any suitable manner, and asindicated in Figure 1 of the drawing, with its open end flush with thesurface of the street or roadway. The signal structure further includesa shaft 2 whose lower end is received by the socket member 1. A shoulder3 is formed upon the lower end of the shaft 2 and the upper end of thesocket 1 when the shaft is in position in the latter. A shOulder i isformed upon the upper intermediate portion of the shaft 2 and a trafficsignal casing 5 is revolubly mounted upon the upper end of the shaft 2.The casing 5 is provided with angularly disposed side surfaces or panels6 and each of the said panels bears a visible sign or legend 7 as forinstance the word Stop and Go as illustrated in Figure l of thedrawings. Other signs or legends may be employed if desired or required.The upper end of the casing 5 is pointed, as at 8, to shed the rain andthe sign legends are set back from the corner portions of the casing 5in order that they may not be obscured by rain, snow or A sleet.

The casing 5 is provided with a central tubular sleeve 9 which receivesand turns on the upper end of the shaft 2. The lower end of this sleeveextends about six inches below the bottom of-the casing and provides aconvenient hand hold to be grasped by the op erator in turning thecasing. The lower end of the sleeve 9 bears against and works upon theshoulder 4.

The device is installed by planting the socket l in the road or streetas hereinbefore described and by slipping the lower end of the shaft 2into the socket. Thus the shaft is held in a vertical position and theofficer may turn the signal casing to bring any particular legend of thesignal to the view of the driver of an approaching vehicle. When no useis required for the signal the shaft 2 is lifted out of the socketmember 1 and the shaft and easing are removed from the roadway orstreet, leaving the socket the fact that the upper end of the socket ngdescr ed t nvent W at is claimed sz-j L In a signal structure, a socketmember open at its upper end, a vertical shaft or 5 standard Whose lowerend isreceived by said socket member, a shoulder formed. on the upperintermediate portion of said standard and a traffic signal casinghavinga central tubular sleeve receiving and revolubly V WILLIAM F.
